brief history of virtualization

1. History of Virtualization
In 2015 I bought a laptop. I don’t know how to use it. I faced many difficulties .but after I am
using laptop we knew everything that how to search it .My teacher assign the topic of
virtualization to whole class. I was just little bit knew about Virtualization.
Virtualization means that we can create thing in virtual not in reality. e.g. version of operating
Systems.
In operating systems we can use hardware virtually by using virtualization technology. Although
the hardware doesn’t exist in reality .It can act as a hardware and can perform all the
functionality .I only knew that knowledge about virtualization. Then the main topic is what is the
history of virtualization.
Virtualization technology start on mainframes that can allow the administrators to avoid the
wastage of processing power. IT administrators who can work on virtualization technology
realized that traditional methods for managing the platform of virtualization is very difficult.
This platform was not so effective for long lasting . we cannot manage dynamic business
requirements by using traditional methods .so they focused and realized that they can innovate
new methods for business or any other things that are related to virtualization .Their demands are
faster growing, demands are high, people demand the security on operating system so that no one
can hack your operating system, installation purpose and upgrading requests were also increased.
Management issues, server handling, recovery issues, automation. for these reasons and demands
from customers a new technology / strategy evolve called virtualization.
Virtualization can change many things .it can change the hardware resources and decrease the
energy cost .it also plays an effective role in clod computing.
